I’m not sure of the exact line you’ve written. “Nivvan mage var jana” isn’t a standard, clearly attested Jain phrase in common stotras I know. If you can share the exact spelling or the source (which scripture or text it comes from), I can complete the line accurately and give the correct arth (meaning) as per Jain tradition.

In brief, “Nivvāṇa” refers to liberation, a central aim in Jain dharma, and many sutras/stotras discuss attaining kevala jnāna (omniscience) and mokṣa (liberation) for the soul. If you intended a specific Stotra or mantra (and whether it’s from Digambar or Śvetāmbar tradition), I can provide the precise text and its meaning once I have the exact line.
